Answer:
Hello!
Okay, so how I solved this answer was I actually of went backwards in order. What I mean by that is I found the scale of 
. Put this division equation into a calculator and then multiply the quotient by 1.0. This should give you an answer of approximately 1.250. 1.250 is the unknown text size for this problem. I took a quiz with this exact same problem and got the answer correct, so I can verify that this is an accurate answer. I hope this helps. Have a lovely day! :)

Answer:
x = 10
Step-by-step explanation:
You can try the answers to see which works. (The first one does.)
Or, you can solve for the variable:
Divide by 75
... (1/5)^(x/5) = 3/75 = 1/25
Recognize that 25 = 5^2, so ...
... (1/5)^(x/5) = (1/5)^2
Equating exponents, you have
... x/5 = 2
... x = 10 . . . . . multiply by 5
_____
You can also start by taking logarithms:
... log(75) +(x/5)log(1/5) = log(3)
... (x/5)log(1/5) = log(3) -log(75) = log(3/75) = log(1/25) . . . . simplify the log
... x/5 = log(1/25)/log(1/5) = 2 . . . . . simplify (or evaluate) the log expression
... x = 10 . . . . . multiply by 5
_____
"Equating exponents" is essentially the same as taking logarithms.
